How to fix "Unable to make private java.time.LocalDateTime(java.time.LocalDate,java.time.LocalTime) accessible"

I'm trying to retrieve a Date format field in a MongoDB collection from a Spring Boot Application. In the Repository I've written the native MongoDB query for the method. When I run the application, I get the errors like:

**org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'bookingHistoryController': Unsatisfied dependency expressed through field 'bookingHistoryService': Error creating bean with name 'bookingHistoryService': Unsatisfied dependency expressed through field 'bookingHistoryRepo': Error creating bean with name 'bookingHistoryRepo' defined in hotelbookingsystem.repositories.BookingHistoryRepo defined in @EnableMongoRepositories declared on MongoRepositoriesRegistrar.EnableMongoRepositoriesConfiguration: Could not create query for public abstract java.util.List otelbookingsystem.repositories.BookingHistoryRepo.findCheckinByCustomerId(java.lang.Integer); Reason: Unable to make private java.time.LocalDateTime(java.time.LocalDate,java.time.LocalTime) accessible: module java.base does not "opens java.time" to unnamed module @77523395** 

And,

**Caused by: java.lang.reflect.InaccessibleObjectException: Unable to make private java.time.LocalDateTime(java.time.LocalDate,java.time.LocalTime) accessible: module java.base does not "opens java.time" to unnamed module @77523395** 

I understand that the issue has something to do with --add-opens java.base/java.time=ALL-UNNAMED but guide me a better way to implement this in IntelliJ.

Java class for the 'bookinghistories' collection in MongoDB.

package hotelbookingsystem.documents; import java.time.LocalDateTime; import org.springframework.data.annotation.Id; import org.springframework.data.mongodb.core.mapping.Document; import org.springframework.data.mongodb.core.mapping.Field; import org.springframework.format.annotation.DateTimeFormat; @Document(collection = "bookinghistories") public class BookingHistory { @Id @Field(name = "_id") private String id; @Field(name = "customer_id") private Integer customerId; @Field(name = "room_number") private Integer roomNumber; @Field(name = "checkin_date") private LocalDateTime checkinDate; @Field(name = "checkout_date") private LocalDateTime checkoutDate; @Field(name = "days_of_stay") private Integer daysOfStay; public BookingHistory(String id, Integer customerId, Integer roomNumber, LocalDateTime checkinDate, LocalDateTime checkoutDate, Integer daysOfStay) { super(); this.id = id; this.customerId = customerId; this.roomNumber = roomNumber; this.checkinDate = checkinDate; this.checkoutDate = checkoutDate; this.daysOfStay = daysOfStay; } public String getId() { return id; } public void setId(String id) { this.id = id; } public Integer getCustomerId() { return customerId; } public void setCustomerId(Integer customerId) { this.customerId = customerId; } public Integer getRoomNumber() { return roomNumber; } public void setRoomNumber(Integer roomNumber) { this.roomNumber = roomNumber; } public LocalDateTime getCheckinDate() { return checkinDate; } public void setCheckinDate(LocalDateTime checkinDate) { this.checkinDate = checkinDate; } public LocalDateTime getCheckoutDate() { return checkoutDate; } public void setCheckoutDate(LocalDateTime checkoutDate) { this.checkoutDate = checkoutDate; } public Integer getDaysOfStay() { return daysOfStay; } public void setDaysOfStay(Integer daysOfStay) { this.daysOfStay = daysOfStay; } } 

The Repository:

package hotelbookingsystem.repositories; import hotelbookingsystem.documents.BookingHistory; import org.springframework.data.mongodb.repository.MongoRepository; import org.springframework.data.mongodb.repository.Query; import java.time.LocalDateTime; import java.util.List; public interface BookingHistoryRepo extends MongoRepository<BookingHistory, Integer> { @Query(value = "{customer_id : ?0}", fields = "{_id: 0, checkin_date: 1}") List<LocalDateTime> findCheckinByCustomerId(Integer customerId); } 

The program is expected to retrieve the list of LocalDateTime Objects for the 'checkin_date' field in MongoDB for the given 'customer_id'.
